Note:
The following procedure can be applied to both AWS

your machine type, for instance, 2 wheel steer machines will
not have steering proximity switches fitted.

WARNING
A raised and badly supported machine can fall on you.
Position the machine on a firm, level surface before
raising one end. Ensure the other end is securely
chocked. Do not rely solely on the machine hydraulics or
jacks to support the machine when working under it.
Disconnect the battery, to prevent the engine being
started while you are beneath the machine.
